Homework Answers
In the above question the right option to be chosen is option a.
Because the option d can't be true as reduction potential of Cu+/Cu is +0.16 V which is positive reduction potential and is higher compared to the reduction potential ( = 0.00 V )of standard hydrogen electrode so reduction will occur predominantly on half cell Cu+/Cu
option c is correct because in a galvanic cell, oxidation occurs in the half cell which has the negative reduction potential or positive oxidation potential.
option e is also correct because the cell which is having higher and positive reduction potential among the two will dominate the other and force it to go through oxidation process.

In a galvanic cell, a spontaneous redox reaction occurs. However the reactants are separated such that the transfer of electrons is forced to occur across a wire. The resulting electricity is measured in volts (V) and is the sum of the potentials of the oxidation and reduction half-reactions: E^o cell = E^o red + E^o ox By reversing the reduction half-reactions, you get the corresponding oxidation half-reaction, for which E^o ox has the opposite sign of E^o red You can...
